Crypto-Lock
From Warhammer 40k - Lexicanum
Crypto-Locks are a type of Adeptus Mechanicus locks, which Archmagos Dominus Cawl created and he based them on the Necrons' own tesseract technology. Cawl improved it with his own improvements, though, so that the Xenos would not be able to open the Crypto-Locks either.[1]
